Laboratory and field evaluation of certain rodenticides against the Egyptian spiny mouse, acomias chirismus

The exposure of the Egyptian spiny mouse A. Cahirinus to certain rodenticides anticoagulants and acute poisons were investigated in laboratory no-choice feeding tests. The 2 most toxic compounds of each anticoagulant, Actosin "C" and acute poisons were chosen for field trials. In the laboratory feeding tests, nearly complete mortality occurred when mice were fed for 4 days on bait containing actosin "C". When bromadiolone was offered for the same period, mortality ranged between 88% and 94%. With acute poisons, thallium sulfate and crimidin caused the same mortality which ranged between 92%-96% after feeding for one day. In the field trials, with actosin "C" effective control was achieved of Acomys populations an 9-11 days but bromadiolone was needed for 15-28 days. The foregoing results indicated that Actosin "C" was effective against A. cahirinus than the other anticoagulant and acute poison compounds because the effect of the antibactriocide sulfachinoxaline

New natural public health insecticide from salvia officinalis L'

5-hydroxy 6,7,3,4-tetramethoxy flavone, the toxic nature plant compound, was isolated from Salvia officinalis and tried against 7 insect species hazardous to public health. The LD50 values indicated that isolated flavone was toxic to house flies than American cockroaches, while it was non-toxic to German cockroaches. But for the LC50 culex adults and human head lice were most susceptible followed by human fleas and bed bugs. A direct parallel relation was found between toxicity and rate of penetration

Efficacy of two first generation anticoagulants against rats in doha sea port

The effectiveness of 2 first generation anticoa tested gulant rodenticides, coumatetralyl and chlorophacinone with sulfaquinoxaline have been in the laboratory against Rattus norvegicus and R. rattus in Qatar. All animals died in 8 days when the 2 species of rats were fed for 4 successive days in the laboratory on bait containing 0.041245% coumatetralyl and after only 6 days when the bait contained 0.005% chlorophacinone + 0.019 sulfaquinoxaline. A field trial against R. norvegicus for 25 days with bait containing 0.04125% coumatetralyl lead to reduction of 93.6%, 92.9% and 90.2% of marks on rat tracking patches, active burrows, trapped rats and unpoisoned bait consumption, respectively. These values were 94.7%, 93.3%, 93.1% and 92.6% when infestation blocks were treated with 0.006% chlorophacinone + 0.019% sulfaquinoxaline. Similar results were achieved against R. rattus fed on coumatetralyl at 0.04125% for the same period, which realized percentage reductions of 91.9, 92.1 and 89.7 in foot prints, trapped rats and food consumption, respectively. These percentage reductions were 93.4, 93.1 and 90.5 when the infestation blocks treated with chlorophacinone 0.006% + sulfaquinoxaline 0.019%
